THERMCSTAT HEATER FOR DESTROYING MOTHS Filed July 10. 1929 All 1 I Ill/lPatented June 24, 1930 PATENT W se 7 HENRY MAFFONI, OF QUEENS VILLAGE,NEW YORK THERMOSTAT HEATER FOR DESTROYING MOTI-IS Application filed July10, 1929. Serial No. 377,103.

This invention relates to a moth and larva exterminator and has for itsobject to provide an apparatus adaptable for containing clothing andother material within a closed casing, and in combination with the saidcasing, a means for heating the interior thereof to a degree sufficientfor destroying the said moths and any insect embryo which may bepresent.

Another object is to provide means for deflecting and directing the heatwaves so as to prevent their direct impingement on the articles Withinthe container. 7

Another feature is a thermostatic control adapted to act upon the heatproducing elements and to simultaneously actuate an air vent in the saidcasing.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a perspective view of a cabinet constructed in the mannerclaimed and described herewith.

Fig. 2 is asection on the line 22 of Fig. 1 and illustrates the interiorof the cabinet and the heating and control elements.

Fig. 3 is a plan section on the line 3-3 of Fig. 2.

Fig. 4 is an enlarged fragmentary sectional view of the deflectormechanism as seen on the line 1-4 of Fig. 2.

Fig. 5 is an enlarged section of the thermostat as seen on the line 5-5of Fig. 2.

Fig. 6 is an enlarged fragment of the easing wall with the air ventshutter mounted thereon and as seen on the line 6-6 of Fig.2.

Fig. 7 is a wiring diagram illustrating the electric circuit as used inthe device claimed.

Referring first to Fig. 1 of the drawings,

. the casing 10, which may be of any suitable material has a door 11, itmay however have double doors, or other means of access if desired.

A thermometer 12 is provided to indicate the interior temperature, andair vents 13 are positioned near to the top of the cabinet. A smallcrank 14 actuates a deflector mechanism which will be described later,and an electric plug socket 141 is adapted for connection with asuitable current supply.

The cabinet is seen in vertical section in Fig. 2 in which the heatingelements are shown built into the base portion. These elements comprisea floor 16 with perforations 17 and resistance element 18, and mountedabove the said floor, the deflectors 19. Lugs 20 pivotally support thesaid deflectors. Lever arms 21 are firmly attached to the deflectors andthese pass downward through slots in the floor and are pivotally securedto the links 22 which connect them with the rocker bars as seen at 23..These elements are all shown in plan view in Fig. 3 and in enlargedtransverse view in Fig. 1 in which it will be seen that the rocker barsare mounted on a rod 24 which extends outward through the casing and hasat its extremity the crank 14:.

Heat from the element 18 passes upward through the perforations l7 andmay be directed toward the side portions of the cabinet by adjusting thedeflectors. This is done by turning the crank 14 and the deflectorpanels move in the arcs 25. It will be seen that the heating elementsare all contained into contact with the element 32 thus closing,

or opening the circuit which applies the heating mechanism. At the sametime it revolves the rod 33 and operates the shutter 34 which is shownin Fig. 6. Other forms of thermostat may be employed to thus actuate theshutter and the circuit cut-olfif desired. The connecting wires of thethermostat are indicated at 34; in Fig. 2.

Hooks 35 are provided for holding the the desired results.

While I have shown and described the preferred embodiment of myinvention, it is to be understood that I do not limit myself to theprecise construction herein disclosed and the right is reserved to allchanges and modi ications coming within the scope of the invention asdefined in the ap ended claims. E:

aving thus described In invention, What I claim as new, and desire tosecure'by United States Letters Patent is 1. In an exterminator of theclass'de scribed, a cabinet, means of access thereto, air vents in the,said cabinet and' a rotatable shutter over the said vents, athermostatic element on the said cabinet and at tached to the wall 0posite to the said vents, a rod connected a t? one end to the saidthermostatic element and'to the said shutter at the other, an electriccontact adjasupply of the heating elements, a movable shutter mounted onthe casing and having apertures alignin with apertures on the casing,and a ro axially mounted on the cent to the said thermostatic elementand adapted'to be opened and closed simultaneously with the operationoft'he said shutter, a heatin element -at the base of the said cabinet,ieflector panels above the said heating element and an electric circuitconnecting the contacts of the said thermostatic element with thecurrent supply of the aforesaid heating element. 2. In an exterminatorof the class described, a cabinet, means of access thereto,

air vents in thesaid cabinet and a rotatable shutter having aperturesaligning with the said vents, a thermostatic element on the said cabinetand attached to the wall opposite to the said vents, a rod connected atone end to the said thermostatic element and to the said shutter at the'other,an electric contact adjacent to the said thermostatic element andadapted to beopened and closed simultaneous! with the operation of saidshutter, a heatin element at the base of the said cabinet, eflectorpanels above the said'heating element and an electric circuit connectingthe contacts of the said thermostatic element with the current supply ofthe aforesaid heating element.

3. In an apparatus of the character described, a casing, elementsadapted to heat the interior thereof, means to direct the said heat indeflected waves within the said casing, means to controlthe degree ofheat by cutting off and re-connecting the current shutter and connectedwith the heat controlling means for co-operating therewith to move saidshutter apertures out of alignment with the said cast a Bree. 1 Intestimony whereo I ave afiixed my signature. 7
